5 Power supply. USB The EFMG8XXSTK can get its power from the standard USB mini port. The MU voltage will be. volts when USB is connected.. Battery There is a socket for a 0mm coin cell battery, which can be used to power the kit. When the USB is disconnected and the battery connect switch is turned on, the EFM and its peripherals is powered by the battery. The VMU voltage is.8 or lower when powered by the battery, depending on the battery voltage. There is a 0.V drop down from the battery voltage. The board controller/aem is not powered by the battery, so the BSP software support library cannot be used on battery power.

6 Reset infrastructure. MU The primary user reset for the MU is the reset button on the MU board. This will only reset the MU. The MU can also be reset by debuggers.. Board controller The board controller can only be reset by pulling and reinserting the USB cable.

7 Peripherals The starter kit has a set of peripherals that showcase some of the features of the EFMG. Be aware that most EFM I/O routed to peripherals are also routed to the breakout pads. This must be taken into consideration when using the breakout pads for your application.. Pushbuttons The kit has two user pushbuttons marked PB0 and PB. They are connected to the EFM, and are debounced by R filters with a time constant of ms.. LEs There are four LEs on the kit marked LE0 to LE. An active high on the respective pins will light the LEs.. L An Energy Micro L display is connected to the EFM. These lines are not shared on the breakout pads. apacitors for the EFMG L boost function is available on the EFMG8XXSTK.. Touch slider A touch slider utilizing the capacitive touch capability is available. It is placed under the two push buttons on the kit, above the "TOUH SLIER" print.. Touch Gecko The Gecko above the pushbuttons, and below the EFM logo, can also be used as a capacitive touch button. 7

8 7 Advanced Energy Monitor 7. Usage The AEM data is collected by the board controller and can be displayed by a P application. For instance, the "Gecko commander" utility contains a "power" command which can dump power data to file. A GUI application for displaying power usage will be available for download from the Energy Micro download section later. 7. AEM theory of operation In order to be able to measure currents ranging from 0.uA to 0mA (db dynamic range), two current sense amplifiers are utilized. The amplifiers measure voltage drop over a small series resistor and translates this into a current. Each amplifier is adjusted for current measurement in a specific range. The ranges for the amplifiers overlap and a change between the two occurs when the current is 00uA. To reduce noise, averaging of the samples is performed before the current measurement is presented in the AEM GUI. uring startup of the kit, a calibration of the AEM is performed. This calibration compensates for the offset error in the sense amplifiers. 7. AEM accuracy and performance The Advanced Energy Monitor is capable of measuring currents in the range of 0.uA to 0mA. For currents above 00uA, the AEM is accurate within 0.mA. When measuring currents below 00uA, the accuracy increases to ua. Even though the absolute accuracy is ua in the sub 00uA range, the AEM is able to detect changes in the current consumption as small as 0nA The measurement bandwidth of the AEM is 0Hz when measuring currents below 00uA and Hz when measuring currents above 00uA. The table below summarizes accuracy of the two current sense amplifiers in different ranges. Table 7.. AEM accuracy urrent range Low gain amplifier accuracy High gain amplifier accuracy 0mA 0.mA ma 0.mA 00uA 0.0mA ua ua 0.uA ua 0.uA Note Having both USB and battery connected may increase the AEM readings. 8

9 8 Board controller The control MU can act as a board controller (B). There is a UART connection between the EFM and the B. The connection is made by setting the bc_en line high. The EFM can then use the BSP to send commands to the B. When bc_en is low, bc_tx and bc_rx can be used by other applications. To use the board controller for your application, the Board Support Package (BSP) must be installed. See the BSP chapter to find out how. Note The board controller is only available when the STK is powered by USB.

10 Board Support Package The Board Support Package (BSP) is a set of source and header files that enables easy access to, and control over some board specific features. ompared to the Energy Micro development kit, the functionality is limited. Unless you need/want some of the functions contained in the BSP, there is really no need to include or use it. The EFM in the Starter Kit can be fully usable without BSP support, and you can use all peripherals in the :\Program Files\Energy Micro\EFM Gecko K\boards\EFM_Gxxx_STK\drivers folder without the BSP. The BSP use EFM peripheral UART0 (TX pin PE0, RX pin PE) on baudrate 08N to communicate with the board controller. Note The BSP is only functional when the Starter Kit is USBpowered, using these function calls under battery power will give unpredictable results.. Installation location When installing the complete software package for the kit, the BSP will be installed under the main installation directory, typically in a location such as :\Program Files\Energy Micro\EFM Gecko K\boards\EFM_Gxxx_STK\bsp\ or something similar (depending on your OS/Windows version). All files in the board support package is prefixed by stk.. Application Programming Interface To use the BSP, include the Starter Kit header file, like this: #include "stk.h" All functions in the BSP are prefixed with STK_. The main initialization routine is defined as void STK_Init(void); and must be called before any access to the STKfunctions. This function call will setup the UART communication channel with a 800 baud rate. This baud rate depends on the current core clock, so correct clock configuration should be set before calling this function. bool STK_Ready(void); Returns true if the board controller is responding. A nonresponding board will either return false, or hang (i.e. if the EFM is powered by the R0 battery cell). float STK_urrent(void);

11 Returns instant current usage in milliamperes. float STK_Voltage(void); Returns instant voltage (VMU) reading in volt. bool STK_EnergyMode(uint8_t em); Informs the board controller about the Energy Mode (sleep mode) we are going into. This information can be used by the board controller to present a richer visual graph for illustrating what the EFM is currently doing. In addition to these main functions, full documentation of the complete API is included in the oxygen/ HTML documentation of the installed package.. Example Applications Under the EFM_Gxxx_STK/examples folder in your installation directory, you will find an example program using the BSP, with corresponding project/makefiles for the supported IEs.. How to include in your own applications The easiest way to include the BSP in your application is to base your work on the example application that use the BSP. The following items are recommended for correct configuration:. Make sure you define the correct part number (i.e. EFMG80F8) as a preprocessor defined symbol. Make sure you define the correct part number (i.e. EFMG80F8) for your project file. Add and include the EFM_MSISfiles (startup_efm.s, system_efm.c, core_cm.c) to your project. Add and include _all_ BSP package.cfiles, with the stkprefix to your project. onfigure include paths to point at the MSIS/M/oreSupport and MSIS/M/eviceSupport/ EnergyMicro/EFM directories. onfigure include paths to point to the EFM_Gxxx_STK/bsp directory Make sure you call "STK_Init()" early at startup, and you should be all set.. hip errata Early versions of the development kit are shipped with EFM Engineering Samples on the MU modules. There has been updates to configuration and reset values that needs to be configured correctly on these early parts. We recommend always starting your application with a call to #include "efm_chip.h" HIP_Init(); in the EFM_MSIS (version..0 or later) core package to ensure correct and stable behavior. See the BSP examples for details. We recommend also to download and read the latest errata from the Energy Micro website for your part number.

12 onnectors. Breakout pads Most I/O except the L pins are routed to the breakout pads at the top and bottom edge of the kit. A.mm (0 mil) pitch pin header can be soldered in place on the pads for easier access. Note Some of the breakout pads are shared by onboard EFM peripherals. The shared pins can be identified by looking at the Shared by column in the tables below. The schematic must be consulted to make sure that it is OK to use a shared pin in your application. Table..

16 ebugging The EFMG8XXSTK has an onboard debugger, and it can be used in different ways to debug the EFM, both on and off kit. Below are descriptions on the different modes. heck the configuration chapter to find out how to change the debug setting. Table.. ebug modes Mode escription ebug MU In this mode the onboard debugger is connected to EFM on the EFMG8XXSTK. ebug IN In this mode the onboard debugger is disconnected, and an external debugger can be connected to debug the EFM on the EFMG8XXSTK. ebug OUT In this mode the onboard debugger can be used to debug an EFM mounted in your own application.. ebugging during battery operation When the EFM is powered by the battery (i.e. the USB is disconnected), the onboard debug functionality is not available. To enable debugging in this mode, connect an external debugger (e.g. another EFMG8XXSTK) to the debug pads in the bottom right corner of the EFMG8XXSTK. These pads are connected directly to the EFM debug interface. Note When the onboard debugger is active, a current of approximately.ua will be added to the AEM measurements.

18 energyaware ommander and Upgrades energyaware ommander is a program that comes with the Gecko K Installer package. It can perform various kit and EFM specific tasks. The program has two modes of operation, either command line or GUI mode. The command line is not backwards compatible with the earlier "Gecko ommander" shell utility, but support all features of that package.. GUI Operation The primary use of energyaware ommander is in the GUI mode. This utility gives the ability to program the EFM, upgrade the kit, lock and unlock devices and more. Some of the features will only work with Energy Micro kits, while other will work with a JLink debugger connected. Press the "F" button, or select the "Help>Help" menu item for a full description.. ommand Line operation Using the command line involves runnig the binary in a command shell, with an appropriate argument, e.g. eaommander.exe help All command line options will be parsed in the other they are given, so multiple commands can be run.

19 . Upgrades Upgrading the kit can be done by using the "Upgrade Kit" script in the start menu. New versions can be downloaded from The script will use energyaware ommander to install the latest available Kit SW package. It is important to upgrade the kit when installing a new SW package, as new energyaware ommander functionality might require kit controller software upgrades. You can also use the energyaware ommander for upgrades. Select the "Kit" icon, use the "Browse" button to select the correct file ending in ".emz", and press the "Install package button". Finally, there is an option at the command line, eaommander.exe install stkappl.emz to explictly install new packages by hand (or within a script).

20 Errata The following sections lists the erratas and known issues for operating the STK. You can read the STK revision on the white label on the back side of the STK. It is in the format "BR00, Rev: Axx".. hip errata You can use energyaware ommander (GUI version) and press the "onnect" button to retrieve EFM revision information. You can also use the command line version: eaommander.exe mcuinfo for the same. ownload the chip errata from for the latest erra updates on your device.. efmlib hip Init routine The efmlib #include "efm_chip.h" HIP_Init() routine will, as far as possible, enable work arounds for chip erratas to make EFM Gecko devices be as software compatible as possible. In some cases, this can introduce increased current. See the device errata and source code for details.. STK Revision Errata Table.. BR00 Revision Errata Revision Problem escription A00A0 The Gecko series of devices has an errata, where going to Energy Mode will drive a pull down on the SWO (Serial Wire Output) UART serial line.
